Using WebApi RoutePrefix attribute on a base controller

Question

I would like all controllers which inherit from AdminBaseApiController to be prefixed with 'admin'.

This works fine of course:

[RoutePrefix("admin")]
public class ToggleController : AdminBaseApiController
{
    [Route("toggle")]
    public HttpResponseMessage Get()
    {
    }
}

However when I move the RoutePrefix("admin") out of the ToggleController and into the AdminBaseApiController (where I want it) - The route fails and I get a 404.

Am I looking at this all wrong? Thanks in advance!

Solution

Support for inheritance has been enabled in Web API 2.2 release...You can take a look at an example in the following Release Notes:
